Low Level Format

Topic

New Reply

I’ve got a HD here which needs some serious talking to. Trouble is, I’ve totally forgotten the bios address entry point for the low level format, I thought it was at C800:0008, bit it isn’t. Does anyone know ?

TIA,

I don’t know either, but out of curiousity, why do you need the bios address entry point for low level format?

Because I’ve got nothing to work with on that computer other than a floppy boot disk, so I’ve gotta go in via debug

Claude, as I recall it can vary based on the manufacturer of the hard drive. If memory serves (it’s been a while) the most common was C800:5.

Some common ones that I had stashed away in my notes, just in case:

• Adaptec G=C800:ccc or G=C800:6
• Scientific Micro Systems/OMTI G=C800:6
• Seagate G=C800:5
• Western Digital G=C800:5[/list] Using Windows over the years has made me lazy. Try looking at the segement offsets between C000:0000 and EC00:0000 in increments of 0400 to see if you can spot something looking like a hard drive’s BIOS signature (such as “©Western Digital” or something similar). Linux sites have a lot of information on this too, if you’re none of this helps.

Thanks Mark.

What used to be a 512Mb HD (no idea why???) is now back to being a 6.8 Gb drive, even the BIOS detects it as such.
